Dear Colleagues,

Apologies for cross postin= g. This is a reminder about Palaeo50= , a horizon scanning workshop at the Long-term Ecology Laboratory of the Oxford Biodiversity Institute on 13th-14th Decemb= er, 2012. The aim of the workshop is to identify the 50 most pressing quest= ions in palaeoecology. What questions should palaeoecology answer in order = to contribute to key areas of its related research agendas? Please note that the deadline for applications to= attend the workshop is 14<= sup>th September 2012.

Whether a palaeoecologist,= ecologist or policy maker, anyone can contribute:

By submitting questions (Deadline 31st October, 2012)<= /li>
= By applying to come to Oxford and select the 50 most pr= essing questions. We would like to bring together a diverse panel of expertise and there is some funding to support postgradu= ate students and early career researchers (Deadline 14th September 2012).

We would appreciate your i= nput in this exercise, either by spreading the word about this workshop by = forwarding this message to your colleagues, by applying, or by coordinating= your group to submit a list of questions that you think are important.

So far the response has been excellent, but we are looking for as diverse a= workshop as possible. We look forward to receiving your questions and appl= ications!

Best wishes,

Alistair Seddon*, Ambroise= Baker* and Anson Mackay**

Assessment of High Efficiency Sorbent= Materials for Application in the Remediation of Radionuclide Contaminated = Groundwater

Although not widely utilised in the UK nuclear indus= try, PRB’s offer great potential due to their ability to sorb specifi= c target species (e.g. caesium, strontium, technetium and uranium) that are= potentially mobile in groundwater.

Data from these studies wil= l enable the type and makeup of materials to be optimised for application o= n specific sites. The effect of emplacement of these materials in contaminated groundwater will also be inv= estigated. Characterisation of the materials following retrieval from groun= dwater to identify any physical/chemical characteristics that will affect p= erformance of the materials in-situ will be determined.
